Has anyone got a TD locking kit I could borrow for a short time?
Friend has a 2.5 TD Landrover, same lump as Omega apparently, and thinks his HG has gone....
Strange failure, he has blown the top out of 3 radiators now, over 6 months. He is reluctant to spend another £250 on another without looking for the real problem.
Not convinced on the HG idea, but he want to do the head to make sure.
I remember something being made from TB's door when he did the job, but has anyone got a kit available we could borrow?
Cheers
-
TB had one....
-
I have the locking kit, and the pdf. I am missing the tool to compress tensioner, and my gargae door will not be dismantled for it.

Any chance of bunging it in the post tomorrow?
If there is I'll check if its of use without the compressor.
Cheers

Cheers matey :)

pm me your addy jimbob

Huge thanks for supplying the Kit Uber fast, and for the technical advice :y
The Head is off,
The gasket 'looks' ok, but does have some dulled areas?
Getting it skimmed before reassemby.
fingers crossed! Trouble is it can go so long before issues, it will be a long time before success can be assumed :-/

You cant skim a diesel head!
-
You need also to check the swirl pots for crackng
-
Why arent they skimmable?
Pots will be thoroughly checked.

Because the swirl pots etc are inserted into the head and as a result it thins the metal on them...it can also cause significant increases in compression.
Many modern heads cant be skimmed.
And anyway, you should not skim a head unless it need it so check its flat first!.
-
Cheers, rethink in progress!
-
As MDTM says, you cannot skim this head. If you have head damage (either caused by hgf or cracking of the head) a replacement head must be sought...
-
He is taking the head to a place who pressure tests em, so will find out if its ok or not that way.
-
Has anyone taken the camshaft of one of these?
Did you use the 'special tool' as described in the manual or just undone the bearing caps progressively and carefully?

only of the head I didn't want. Just undid them, no issues, but then its never going back together as its slowly going to landfill
-
Right, he has just got it back from the engineers....
It held pressure, but was slightly warped, so they skimmed it without his consent!
They said it was ok on this one as there are 2 types of 2.5 TD...
This one has recessed swirl pots, and was therefore ok to skim. :-/
Reassembly time now, and he is really hoping for the best.

both vx docs and bm docs say no to skim... ...but if it cures his prob :y
-
might need to adjust hg to bring compression ratio back to what it should be

Yes, you and Mark both said, the manual says.....but it does seem skimmable form what he said.
Were your swirl pots recessed or sticky out?

both heads (u25dt and x25dt) recessed
-
Thy sit almost flush....trouble is skimming reduces the amount of metal holding thm in and these are prone to cracking at the best of times!
The other issue is the increase in compression ratio!
-
Have seen something about 2 different thinknesses of HG
Guess its hope for the best time, and hope they havent taken much off!
Back to the original issue of blowing a hole in the rad tank, so you think this could cause it? I would have thought a hose, or most likely the header cap would go 1st?
-
Depends if the rad was on its way out.
Orig rad on mine looks like its had a repair (they are expensive). Still in garage if he wants it, but not really postable.

It was the 3rd rad to go this way! in 6 months!
Sure you dont wanna come to the Chester Meet ;)
Lol, its in a Range Rover, so doubt it would fit?

Mine normally did the cap. Got through loads of them. Also did a bodged bolt closing off extra outlet when I used a v6 bottle once :o
-
Got me thinking, is the rad easily accessible? If so any chance of the measurements, if they are the same.....they are on TC ;)

TD rad is on TC iirc, £234+VAT 2yrs ago. Strange how that figure sticks in my head, possibly the reluctance to hand over the money >:(

Close, £235 retail, £193 TC.....he had been quoted about £250+ at Landrover. I wonder if they are the same :-/

No, Vx one unique.
Get specs from here

cheap rads, but never seemed to be able to supply TD one after I ordered one...

It is all back together and running beautifully!
7 Thou off the head
Valves ground
Injectors cleaned
Various other bits replaced or cleaned whilst it was open.
Radiator is to be repaired, and take it from there.
Have you kit Jaime, so will keep it safe till someone wants it, or I see you.
Al says you were concerned one bit was not flat / true? He has checked with an engineers level and it is fine :y Huge thanks for the loan of that.
Time will tell :y

Good news, lets hope it does hold together. Though if he got it skimmed, that would overcome my worry anyway.
-
Well, it dumped its coolant again :'(
A new, better modified rad, with a brass tank is being installed.
He is REALLY hoping that fixes it for good.
Looks like the head's were fine after all.
-
Hmm, has the water pump been changed for a metal one? cos this does sound like pump impellor(plastic) coming loose when hot?
